Embodiment one
Present embodiment is that example describes with MTC equipment; At Long Term Evolution (LTE; Long-TermEvolution) in the system, MTC equipment is through base station 1 access network and be in connection status, and control MTC equipment is initiated the process of service request in the present embodiment; As shown in Figure 2, specifically can may further comprise the steps:
Step 201: because numerous MTC equipment and H2H equipment access network; Cause that the MME load surpasses predetermined threshold; MME sends overload beginning (OverloadStart) signaling to all base stations (comprising base station 1) of self connection, and all MTC equipment initiation new business are forbidden in all base stations that require self to connect.
Step 202: base station 1 receives after overload that said MME sends begins signaling, said overload is begun signaling resolve, and obtains the load information of said MME;
Step 203: base station 1 is according to the load information that is obtained; In system message (System Information), increase and be used to indicate the information of forbidding all MTC equipment initiation service request; Upgrade the current said system message that will broadcast, and updated system messages is broadcast to each the MTC equipment that is in connected state;
Here; Be used to indicate and forbid that it specifically can be that value is the indication information of True or False that all MTC equipment are initiated the information of service request; Can be provided with in advance, when value was True, all MTC equipment initiation service request were forbidden in said information representation; When value was False, said information representation allowed all MTC equipment to initiate service request.
Particularly, the information of new service request is initiated through the said MTC equipment of forbidding being in connected state of system message broadcasting in base station 1, can avoid MTC equipment to initiate the load that new business increases core net.
Here; Control simultaneously is in each MTC equipment initiation service request of Idle state if desired; Base station 1 can be at the MTC equipment that is in Idle state after self sends RRC connection request (RRC ConnectionRequest); RRC connects refusal (RRC Connection Reject) signaling to its feedback, refuses it and inserts, and initiates service request thereby control is in the MTC equipment of Idle state.
Step 204: the rrc layer of each MTC equipment receives the system message of said base station 1 broadcasting; And the information that the MTC equipment that forbidding of comprising in the said system message is in connected state is initiated new service request is delivered to the NAS layer of said MTC equipment; The NAS layer of MTC equipment is preserved the information that the MTC equipment of forbidding being in connected state is initiated new service request; In the time new service request will being initiated, in view of the above, do not carry out the initiation operation of this new service request.
Step 205: after a period of time, after MME recovered normal operating state, MME sent overload to all base stations (comprising base station 1) that self connect and stops (Overload Stop) signaling;
Step 206: base station 1 receives said overload and stops signaling; Said overload is stopped signaling resolving; Obtain the load information of said MME,, delete the indication information that forbidding in the current system message initiate service request according to said load information; The indication information of perhaps forbidding in the current system message being initiated service request replaces to the indication information that allows to initiate service request; Perhaps, upgrade current system message, and updated system messages is broadcast to MTC equipment forbidding in the current system message that the indication information value of initiating service request is revised as " False ";
After the rrc layer of step 207:MTC equipment receives said system message, transmit this system message to its NAS layer, the NAS layer of MTC equipment upgrades the system message that self preserves, and when the new business demand is arranged, initiates the corresponding business request.
Here; The process that said MTC equipment is initiated service request is following: because MTC equipment is in connected state at this moment; The last course rrc layer of MTC equipment sends the NAS signaling of service request, and (UL Information Transfer) sends to base station 1 through the uplink information transmission, sends to MME by base station 1 again; Under the situation of resource grant, MME will dispose the parameter of new requested service so that MTC equipment is set up new business.
Present embodiment is equally applicable to WCDMA (WCDMA, Wideband Code DivisionMultiple Access) system, and implementation procedure is basic identical; Institute is not both, and in the WCDMA system, what send said system message is radio network controller; Particularly; Radio network controller is provided with the information that the MTC equipment of forbidding being in connected state is initiated new service request in its system message, after MTC equipment is received system message, this information is passed to the upper strata of MTC equipment; MTC equipment just can not initiated new service request once more, can avoid MTC equipment to initiate the load that new business increases core net like this.
Embodiment two
Present embodiment is that example describes with H2H equipment, and in the LTE system, H2H equipment is in connection status through behind 2 access networks of base station, and control H2H equipment is initiated the process of service request in the present embodiment, and is as shown in Figure 3, specifically can may further comprise the steps:
Step 301: because numerous MTC equipment and H2H equipment access network, cause base station 2 overloads, the terminal that the terminal that base station 2 decision restriction accesses are new and forbidding is in connected state initiates to allow the business that postpones again.
Step 302: base station 2 increases to be used to indicate in its system message forbids that the initiation of H2H equipment allows the information of deferred traffic, upgrades the current system message that will broadcast, and updated system messages is broadcast to each the H2H equipment that is in connected state;
Here, be used to indicate the information of forbidding H2H equipment initiation permission deferred traffic specifically can be used to indicate the binding hours (BarringTime) of forbidding that H2H equipment is initiated to allow the restriction factor (BarringFactor) of deferred traffic and/or forbidden H2H equipment initiation permission deferred traffic.
The rrc layer of step 303:H2H equipment receives said system message, and received indication is forbidden that the initiation of H2H equipment allows the information of deferred traffic to be delivered to the NAS layer preservation of self.
When the NAS layer of step 304:H2H equipment will be initiated service request, forbid that according to including in the system message to be used to indicate the initiation of H2H equipment allows the information of deferred traffic, carry out or do not carry out the initiation operation of said business.
Particularly, when the NAS layer of H2H equipment will initiate to allow the deferred traffic request, detect to include in the system message of preservation to be used to indicate and forbid that H2H equipment initiates to allow the information of deferred traffic, in view of the above, carry out or do not carry out the initiation operation that allows deferred traffic:
